Some think it is for GPS Some want the best Maps! But others want COMMUNICATIONS! Not just GPS Vehicle Tracking! Can you see APRS Stations? No! Can you see APRS network? No! APRS is a registered trademark Bob Bruninga, WB4APR 10 What is APRS? APRS = Automatic Packet Reporting System (not position tracking!) APRS was developed in the late 1980's for local tactical digital communications, situational awareness and TWO-WAY information exchange Messages + maps for OBJECTS – everyone sees the same situation and Network Connectivity Not just GPS Vehicle Tracking! APRS is a registered trademark Bob Bruninga, WB4APR 11 The APRS Network Information exchange between everyone Aa Digipeaters And to the Internet Gateway Multiple Hops APRS is a registered trademark Bob Bruninga, WB4APR 12 Global Mobile and Portable Connectivity APRS is a registered trademark Bob Bruninga, WB4APR 13 Seeing the Network (PHG data shows relative station performance) 50 mi APRS is a registered trademark Bob Bruninga, WB4APR 14 Seeing the Situation (Symbol Atributes) APRS is a registered trademark Bob Bruninga, WB4APR 15 Symbol Atributes The original Overlayable Symbols Since April 2007, all alternate symbols may now have overlays Note, some popular “aprs” programs do not display ANY of these 11 attributes on any map!

(Humans communicating INFO with Humans) Immediate local digital and graphical information exchange between all participants in a local area or event. This includes: Positions of all stations and objects Status of all stations Messages, Bulletins and Announcements Weather data and telemetry DF bearings and signal strengths for quick transmitter hunting RF Connectivity plots of all stations Local OBJECTS on a common map display for all users Local Freqs, IRLP, ECHOlink, Winlink, Nets, Meetings Typical applications are: Routine local awareness of all ham radio events and assets around you Marathons, races, events and public service Search and rescue Family communications and tracking and one-line emails Mobile-to-mobile global text messaging Weather data exchange and display Efficient multi-user Satellite communications APRS is a registered trademark Bob Bruninga, WB4APR 23 Scope of APRS Over 40,000 users worldwide. RELAYS every 20-30 mi called “digipeaters.” All linked by home station Igates Global links by Amateur Satellites Thousands of Weather stations Telemetry and data everywhere But, only 2% of local ham radio users… (a side show)… APRS is a registered trademark Bob Bruninga, WB4APR 24 APRS, Maps, Events and Objects! Dayton Hamvention APRS is a registered trademark Bob Bruninga, WB4APR 25 Various APRS Stations (two-way) APRStt now APRS is a Network intended for real-time Tactical INFORMATION exchange. This means TWO-WAY. APRS is a registered trademark Bob Bruninga, WB4APR 26 TRACKERS (should be two-way) One-way APRS is not normally recommended. APRS is a Network. We want good 2-way communications among all participants for maximum utility. Trackers have no APRS data display. So the receiver should be tuned to a beaconed Voice frequency so the operator can be involved in the Net! One-way trackers are good for non-manned assets at large movement events.. Not as the only APRS asset for a ham. Trackers may be his 2nd, 3rd or 4th unit for APRS support… not his 1st!

APRS is a registered trademark Bob Bruninga, WB4APR 31 APRS MisConceptions! See APRS-tactical.html That APRS is just Vehicle Tracking instead of a Real-Time Information Distribution System. That APRS is dependent on GPS for its value (GPS is not needed. See Objects). Failure to use the APRS built-in Mile-Marks for tracking all other non-APRS mobiles. Using APRS clients that only do maps and ignored too many of the APRS fundamentals. Ignored the fundamental Decay Algorithm to accelerate new data, and decay old data! Failure to understand the importance of OBJECTS: . See Objects 101 and Operations Failure to use real-time messaging: . See Messages 101 and Message Operations Failure to implement the original APRS Centralized Common Bulletin Board concept. Not understanding the APRS operator’s role as a Data Input (Objects, Bulletins and Messages) Not using the D7 and D700 as data entry and clipboard display units at field events. Too much focus on Large Screen Displays –vs- Individual Operator displays for events. Failure to display APRS symbols with all their attributes and colors without clicking them Failure to manage the network by adjusting the local digipeater for the situation at hand. Not realizing the importance of Voice Operating frequencies in APRS. APRS is a registered trademark Bob Bruninga, WB4APR 32 APRS Growth Opportunities! Global Email Done!

(For all mobiles!) Voice Alert is effectively 3rd Radio channel for the D7 and D700 APRS radios By setting the APRS Band A to CTSS-100, but keeping the volume turned up: * You wont hear any packets on 144.39 * But you will hear a voice call using PL-100 on 144.39 And you will hear* an occasional Ping packet if another D700 comes in line-of-site to you, like a proximity radar alerting you to local presence.

Direction & Distance Frequency and Tone APRS is a registered trademark Bob Bruninga, WB4APR 55 The New-N Paradigm 2005 Factor of 3 to 5 improvement! APRS Generic Paths evolved over 13 years and the presence of many old legacy formats and procedures were really bogging down the network making it saturated and unreliable in busy areas. In 2005 all old paths were declared obsolete (RELAY & WIDE) and the entire APRS system in the US was then focused only on the WIDEnN type of generic paths with small values of N. WIDEn-N goes N hops outward in all directions.
